Application led July 13,

To all whom t may concern Be it known that I, FRANK RAnnoHovsKY, a. citizen of theUnited States, and resident oi Milwaukee, in the county of Milwaukee and State of Vvisconsin, have invented certain new and vuseful improvements in Eundle Tiers; and he hereby declares that the following is a full, clear, and exact description thereof.

My invention pertains to new and useful improvements in semi-automatic machines for tying bundlesa and has special reference to means for tying bunches of vegetables7 such as radishes, onions and the like.

Heretofore it has been gene-rally customary to bunch radishes and similar vegetables by hand, which is obviously a comparatively slow process, especially when each individual bunch must be separately tied. Consequently it is the primary object oi this invention to provide a simply constructed tying machine by means ot which bunches of vegetables can be rapidly and eiectively tied.

An additional object ot this invention is to provide a machine of this character of a semi-automatic nature which can be readily actuated when necessary by one toot of the operator so as to leave the hands tree for feeding bunches or" vegetables to the tying mechanism.

lt is also an objectief this invention to provide a simply constructed machine, the large majority of the parts of which may be made oi' sheet metal stampings which can be readily assembled to construct a relatively inexpensive tying means.

It is likewise an object oi this invention to provide a novel and simply constructed cord holding device for the needle portion ofthe machine whereby the cord is always retained taut. f l* f lith these general objects in view and others which willbecome evident as the description proceeds, thevinvention resides in the novel `features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.

Figure 24 is a substantially horizont-al sectional view on the plane of the line Qe24c of Figure 1.

Referring more particularly to the drawings, it will be seen, especially from Figure 1, that my improved machine is of a relatively compact design and all of the various operating parts are within the easy reach of the operator who stands or is seated in front of the machine in position to feed bunches of vegetables or other articles to be tied on to the work table l, and to move the actuating foot lever 2, the same having a pedal 3 at its lower or free end. These parts and other operating mechanisms of the machine are carried upon the support which comprises a base 4, a substantially vertical standard 5, and a laterally support arm 6. The standard 5 is braced by a brace bar 7 and carries a cord receptacle 3 in which a ball of twine or the like may behoused and from which the tying cord may be fed. rIhe major portion o1 the support arm 6 extends rear wardly, and that part which projects forwardly of the standard 5 has a table carrying arm 9 fixed thereto, the same extending upwardly and forwardly in an inclined position and having a work table bracket 10 pivoted thereto. Normally ,the work table, which is in the form of a pair of spaced sheet metal plates, is raised,'but as soon as the articles to be tied are placed thereon it is depressed to the dotted line position shown in Figure. 1. A contractile spring 11 holds the table in its normal elevated position.

A needle 12 in the form of an arcuate bar worlis between the plates forming the work table and is mounted on one end of a needle lever arm 13, this arm being pivoted intermediate its end of the table carrying arm 9. rlhe end portion of the needle lever arm opposite the end to which the needle 12 is secured has an arcuate pin engaging track 14 over which a pin 15 on a needle operating lever 16 is slid. This lever 16 is pivoted intermediate its ends on the support arm 6, and its fulcrum point is relatively adj acent, although below the pivot 17 of the actuating` Vfoot lever 13.

The levers 2 and 16 are normally connect ed together for simultaneous movement, but are automatically releasable after the foot lever 2 has been moved a predetermined eX- tent. For instance the lever 2 has a latch 18 pivoted thereto, one end of which is engageable with cam shaped latch lug 19 on the lever' 16. A spring 20 normally retains the latch in engagement with the lug, and the pin21v'on the lever 2 prevents the latch 18 from dropping below a predetermined Y operative point. Thus after the lever 2 has been moved a predetermined distance in the direction of the arrow in Figure 1, the latch 16 will ride ofi' of' the lug 19 to disconnect said levers. Upon release of the foot pedal anism anda guide track for the rack carriage 241. rThe latter is shifted longitudinally of the table 23 simultaneously with theV movement of the levers 2 and 16 and the Opf eration of the needle lever arm 13. In other words a rack carriage lever 211V is pivoted intermediate its ends to the support arm 6, and has its lower end connected vby a linlr 25 with the similar lower end of the needle operating lever 16, its other end having a link connection 26 with an ear 27 depending from said rack carriage 24. A retracting spring 23 connected' with the needle lever arm 13, and with the rack carrier arm 2a, returns both these elements to normal inactive position at the end o1 the operation ot the machine, the needle lever arm 13 'being limited in its retraeting movementby a stop 29, Awhile the lever 211 is similarly afiected by a stop 30, one of the mechanisms carried on the table 23 is a cord retaining means for holding the free end of the cord C while the portion adjacent said ends is being tied about the bundle. As shown in the detailed views, Figures 9V to 13 inclusive,this means comprises a stationary guide finger 31 and a pair of' slightly spaced stationary cord retz'tining fingers 32, said ngers having a pivoted cooperating oord Vretaining finger 33 movable therebetween and toward and away from the guide finger 31. In other words, the pair of stationary lingers 32 and the guide finger 31 are spaced apart to permit the Aend of the needle 12 to enter therebetween and to dispose the `end portion of' the cord Con the pivoted retaining finger 33` adjacent the hooked end'34: thereof. lThe pivoted finger 33 is fulcrumed at its upper end between the upper end portions of the fingers 32, and these stationary fingers 32 togetherwithY the ,Y guide 31 are fixed in a frame 35. The latn erally extending spaced flanges 36 which form a part of' this frame 35 provide pivotV ears for cooperation with similar ears 37 on the table 23,'the pivot rod 33 extending through all of these ears whereby the frame ico 35 and the partsY carried thereby Vcan rock Y forwardly and rearwardly with respect to said table 23 and thus move the activeVV ends of the cord retainingfingers toward and away from the lmotting mechanism to be hereinafter more particularly described.

Proper rocking of the pivoted cord retaining finger 33 is obtained throughthe rotation of the eccentric shaft 39, same being journaled in suitable bearings on the table 23 and having an eccentric 410 on its lower end, the` pin of which is movable in the slot l11 ofa rocking plate 42; the latter entendsV 'from and forms a part of' the pivotedfinger 33. Upon rotation of the shaft 39, the finger 33 will be obviously rocked baclr'and forth y. on its pivot, and the frame 35 will likewiseV be given a pendulous movement in the plane at right angles to the plane of movement to the former and against theV tension of a position by a spring 66.

spring 43. As shown in Figures 1 and 9 the spring 43 acts on the pin 44 projected from frame 35.

A gear 45 is fixed to the upper end of the eccentric shaft 39 above the table 23 and is adapted to have a rack 46 intermittently engaged therewith, this rack being carried by an upper rack bar 47. The hereinbefore mentioned rack carriage 24 has this rack bar 47 mounted thereon as well as the lowerrack bar 48. The rack bar 47 is effectively guided during its reciprocation, and especially during the time when the rack 46 is out of engagement with the gear 45, being operatively engaged between one edge of said bar 47 and the periphery of a guide collar 49.

The knotted mechanism mounted on the forward end of the table 23 is carried by the lower end of the knotting shaft 50, said end of the shaft being journaled in a bearing on the free end of a bracket arm 51, whereas the upper end is rotatively mounted in a bearing opening in the table 23. The knotter consists of a stationary knotting finger 52 and a pivoted knotting finger 53, this latter finger having an upwardly extending rocking arm 54 which is engageable with the periphery of a cani 55. formed on the lower end of said bracket arm 51. rThe cam 55 being stationary and the shaft 50 rotatable, itis V0b-y vious at predetermined intervals that the ends of the normally engaged knotting lingers 52 and 53 are spaced apart to permit a portion of the cord C to enter therebetween (see Figures 2O and 21). kl/Vhen the cam 55 does not hold the knotting fingers spaced apart, they are held tightly together by the tension ofV a spring` 56, which is located in a bore 57 in the lower end ofthe shaft 50 and bears against a, plunger 58. The latter in turn contacts with a portion of thepivoted finger 53 as indicated most clearly .in Figure 15. l 1; Y y

As in the case of the eccentric shaft 39, the knotting shaft 50 is rotated intermittently by the reciprocation of the rack carriage 24 and the lower rack bar 48. This bar 48 has a rack 59 of predetermined length fixed thereon for intermittent engagement with a` gear 60 on the shaft 50. F ixed'to the gear 60 and forming a part thereof is a collar 61, the periphery of which -is engageable by one edge ofthe rack bar 48 for the same purpose as the conduct between the rack bar 47 and the collar 49. The table 23 likewise carries a cutting mechanism for severing the cord C and in proper time, and the knife element 62 of this means is disposed on one end of the stripper plate 63, this part in turn being carried by an intermediate stripper arm 64. As indicated in Figure 5 this stripper arm 64 is fulcrumed to a supporting plate 65 forming` one portion'of the table 23 and is normally urged to one The cord being fed across the stripper 63 is guided into the opening 63 thereof by guide surfaces 67 formed thereon, stationary guide arms 68 further aiding in this respect. As shown in Figures 1 and 2 these guide arms 68 are secured to a bracket 69 and extended forwardly of the free end of the table 23 and over the space between the plates forming the table 1. The stripper plate 63 together with the knife 62 which is mounted thereon is shifted at the proper time by the movement of a rocker 70 against the upper free end of the stripper arm 64, this portion of the arm being` extended above the table 23. The rocker 70 is pivoted on the bracket 71 and is intermittently actuated by the engagement of the rocker trip 72 therewith. As shown in Figure 2 the rocker trip 72 is adapted to be contacted with the rocker 70 when the carriage 24 is, shifted forwardly on theA table 23. A

The cord tensioning device of the needle 12 consists of a curved spring plate 73 adjustably secured at one end to the needle 12 by the screw 74. The other end of the plate 73 is free and bears against the free end of the needle as shown in Figures 7 and 8. Thus the cord C can be fed through an eye 75 adjacent the base of the needle and through the second eye 7 6 relatively close to the free end of said needle, after which it is run beneath the free end of the spring plate 7 3 and between the pins 77 and 7 8 extending laterally from the needle and through the same. Between the receptacle 8 and the needle 12 the cord is led through a twine guide 7 9 as shown in Figure l.

In the operation of my invention the per son working the same stands or is seated in front of the machine as hereinbefore inentioned. After the needle is threaded as above described, the operator moves the actuating foot lever rearwardly, which action will rock the needle lever arm 13 and cause the needle 12 to be projected between the guides 68, over the guide surfaces 67 and between the guide finger 3l and the cord ra 'taining fingers 32 when the movable linger 33V is positioned as shown in Figure 9. .fi-.t this time finger 33 is shifted to the position shown in Figure 10, whereupon the cord will be caught between the hooked end 34 of the same and the coacting surface of the stationary fingers 33 (see Figure 12). Upon the gripping of the free end portion of the'cord in this manner further movement of the lever 2 will cause the release of the latch 18 from the lug 19 and permit the simultaneous return of the carriage 24 and the needle 12, and likewise the retraction of the carriage again shifts the pivoted finger 33 to the normal position as indicated in Figures 9 and 11. The end of the cord, however, is still retained by the fingers 32 and 33 and is prevented from lateral movement with the finger 83 by the engagement with lugs 3st on the lingers 372; VThus the Cord C after this initial manipulation of the lever 2 will be disposedas shownin 'lull onthe planeet the line in Figure l.

rilhe operator then takes abuncli o'l vegetablesto be tied and iorces the saine belowthe guides GS and between these parts and the work table l, the latter being depressed as indicatedby the broken lines in the last inentioned'gure. The cord will be likewise de- .Y clockwise direction.

pressed and engaged with a portion of the bunch which is being tied so that when the lever'2 is again operated to throw the needle 12towards the rear'ol the machine as hereinbefore mentioned and as shown inl Figure 17, the bunch'will be completely encircled by the'cord. Inasmuch asthe cordis again brought intoclose proximity to the retaining fingers 32 andB- it will becaught and gripped as was theV free end ilj ortion-thereot By reference to vF igurel, theexact manner ol positioning and circling thecord about the bundlemay be seen, this view showing Vthe holding or" the free end of the cord and the intermediate portion thereof by the iingers` 32 and 33,while the portions olf the cord there adjacent are disposed over the -knottingfiingers- Just prior to the' second engagement of the cord by theretaining 'hngers-32 and 83 the uppermost section of the lcordis'pressed against the bundle and held securely by plunger engaging arm 80.

Figures 18 to 23 illustrate the several operations ot the portions of the machine which are ldirectly responsible `for the `torniation cifra bunch loop L For insta-nce Figure 18 shows a single strand o'l cord held by .the jaws of the retaining lingers@VV and 33 and trainedover theknotting fingers 52 and 53. On the second manipulation of the needle l2 two strands of cordwillbe held by, lingers 32 and 33 and trained'overthe knotting lingers 52 and-53 as shownin Figure'l9. the movement of the carriage 24;

causes the rotation ot the shaft in a couuter clock wise direction, thelfnotting lingers 52 and 53 will be similarlyturned'as shown by the arrows in Eigures 19 and 20, and

simultaneously opened by the cam 55 so that on the completionv of one revolution ot said shaft thedouble strands of cord Vwiilbey wrapped about the knotting fingers-as indicated in Figure 20. ln other words, one part of the double strand will be` disposed-around Vsuch fingers and another part will be ot the stripper arm 64, the knife 62 will be project-ed asindicated in Figure-21 and the 'l` iat is, upon Vworking stripperl plate will move as in Figure 22T so as to `pull that; portion otthe` double strand of cord held between theV knotting ngersV througli'the other loop of the doublefstraiul whichl isidisposed around said fingers and thus complete the knot. All of'these operations V'are carriedv out during the projectionV ot' the carriage 2li forwardlyon the table-23. On the automatic return movement of said carriage due to the disengagement of theA latch 1S from its llug l9all of the parts actuated by the shifting of the carriage will be returned to normal inactive positions;V In this manner the Vlrnotting shaft 50 is re-V volved in the clockwise direction and the knotting fingers spaced apart to disengage the knot which has beenltormed'on-theloop L. i (See Figure 23),. bviouslyv immedi-Y ately after the return of the parts to positions oit rest, a second bunch of vegetables or thelikecan be similarly tied uponbeing t placed on Vthe worktableV l and the actuating foot-lever moved bythe operator.
